Earlier, Armenian Prime Minister Nikol Pashinyan accused the Turkish military of controlling Azerbaijan's military operations in Nagorno-Karrabakh, and alleged that Ankara has deployed jihadist mercenaries from Syria to support the fight against Armenian forces.

Turkish President Recep Tayyip Erdogan has urged Baku to continue to pursue its offensive in Nagorno-Karabakh to a triumphant conclusion.

"Azerbaijan has already liberated a vast territory. I hope it will keep fighting until all its lands in Karabakh are freed," Erdogan said in an address broadcast on Twitter on Friday.

The Turkish president noted that Turkey supports "friendly and fraternal Azerbaijan in all possible ways," and would continue to do so in the future.

No Peace Without Turkish Withdrawal

Earlier, in an interview with the Globe and Mail, Armenian Prime Minister Nikol Pashinyan said that Turkey's exit from the southern Caucasus would be a necessary condition for peace in Nagorno-Karabakh. 

Pashinyan added that it was now up to Turkey's NATO allies to provide an explanation as to why Ankara is involved in the Karabakh conflict.

"Turkey's military personnel and the Turkish armed forces are directly engaged in the hostilities. Turkey's NATO allies must explain why these [Turkish] F-16 jets are shelling towns and villages in Nagorno-Karabakh and killing civilian populations," he said, referring to reports from earlier this week that an Armenian air force jet had downed a Turkish fighter. Turkey denied those reports.

Pashinyan suggested that Western countries should rethink the sale of arms to Turkey amid reports that they were being used by the Azerbaijani side in Nagorno-Karabakh.

In a series of tweets, Pashinyan also accused Ankara of returning to the South Caucasus "to continue the Armenian Genocide," and said that "Armenia and the Armenians of the South Caucasus are the last remaining obstacle on the way of continued Turkish expansion toward the North, the North East, and the East, and the realization of its imperialistic dream."

In a recent interview with Le Figaro, Pashinyan said that Yerevan has evidence that the Turkish military was controlling Azerbaijan's military operations in Nagorno-Karabakh, and suggested that Ankara be kicked out of the Organisation for Security and Co-operation in Europe (OSCE) due to its 'aggressive and biased' position on the Nagorno-Karabakh conflict.

On Thursday, Erdogan said that the OSCE Minsk Group tasked with negotiating a solution to the Nagorno-Karabakh conflict has no right to call for a ceasefire, and said that the organisation should demand that Armenia put an end to its "occupation" of the breakaway Azerbaijani region instead.

Both Paris and Moscow have expressed concern over reports of illegal armed formations being transferred to Nagorno-Karabakh by Turkey from Middle Eastern conflict zones including Syria and Libya to take part in the fighting against Armenian forces. 

In his remarks Friday, Pashinyan reiterated the claims about the transfer of jihadist militias, and stressed that the population of Nagorno-Karabakh cannot be "unprotected, facing terrorists and extremists."
